Just keep repeating the "Serenity Prayer. "God grant me the Serenity to accept the things I cannot change, the energy and courage to change the things I can, and the wisdom to know the difference."
We MUST accept everything that happens to us no matter if it's pain, impairment or death.
I play chess at Chess.com every day to keep my mind active, I play Civilization VI at Steam.com every day, I walk TWO walks of 2,000 steps every day, I drink 8 glasses of juice, I take 3,000 mg of Tylenol and 200 mg of Gabapentin to relieve my pain. If our minds go under, just play games and amuse yourself with artificial dreams and you will make it until you will be able to accept death.
Father Death (Jesus Christ) takes us ALL in the end and we cease to exist ending all problems.
